Buying Guide: How to Choose the Best Power Bank for Backpacking & Hiking Trips
When I’m packing for a multi-day trek, every ounce matters. My power bank is a non-negotiable piece of gear for safety and navigation, so choosing the right one is critical. It’s not just about the biggest battery; it’s about finding the perfect balance of capacity, weight, and durability for the trail. Here’s what I always consider before buying a new one.
First, let’s talk capacity, measured in watt-hours (Wh) or milliamp-hours (mAh). This tells you how much juice the power bank holds. For a weekend trip, a 10,000mAh bank is usually enough to fully charge my phone a couple of times. For longer adventures, I look at 20,000mAh or even larger. But here’s the catch: more capacity means more weight and size. A 20,000mAh bank is essentially twice as heavy as a 10,000mAh one. I always ask myself, “How many charges do I really need?” to avoid carrying unnecessary weight.
Next is portability. A heavy, brick-like power bank is a burden. I look for models that are slim and lightweight. The shape is also important; a long, narrow bank often fits better in a backpack’s side pocket than a chunky square one. Durability is a close second. The best power bank for backpacking & hiking trips should be tough. I prefer models with a robust, rubberized exterior that can handle a drop onto a rock or being jostled in my pack. Some even come with an IP67 waterproof and dustproof rating, which gives me peace of mind during river crossings or in a downpour.
Finally, I check the output and input specs. For output, I want at least one USB-C Power Delivery (PD) port. This allows for fast charging of modern phones and, crucially, can power my USB-C rechargeable headlamp or GPS device. For input, a USB-C port for recharging the bank itself is a must; it’s much faster than old Micro-USB. If I’m on a long thru-hike, I might even consider a model with built-in solar panels, though I see these more as a trickle-charge backup rather than a primary charging method. The key is finding a unit that balances these features without breaking the bank or my back.
Frequently Asked Questions
How many times can a 20,000mAh power bank charge my phone?
This depends on your phone’s battery capacity. Most modern smartphones have batteries between 4,000mAh and 5,000mAh. Accounting for some energy loss during the charging process (about 20-30%), a 20,000mAh power bank should give you approximately four to five full charges for a standard phone. It’s perfect for a week-long trip if you’re careful with your phone usage, using it mainly for photos, GPS, and emergencies.
Can I take a power bank on a plane?
Yes, you can, but there are strict rules. The Federal Aviation Administration (FAA) and most international agencies limit power banks in carry-on luggage. The capacity must not exceed 100 watt-hours (Wh). For a typical power bank, that’s about 27,000mAh. You can usually bring two larger power banks between 101-160 Wh with airline approval. Power banks are never allowed in checked baggage due to fire risk. Always check your specific airline’s latest regulations before you fly.
Are solar-powered power banks worth it for hiking?
In my experience, they are a mixed bag. The small panels built into a power bank are not very efficient. To get a meaningful charge, you’d need to leave it in direct sunlight for many hours, which isn’t always practical on a moving trail. They add weight and cost for a feature that might only provide a small trickle of power. I find it more reliable to carry a power bank with enough capacity for my trip and consider a separate, larger foldable solar panel only for very long, sunny expeditions where I can set up camp for a whole day.
What’s the difference between mAh and Wh?
mAh (milliamp-hour) is the most common rating you’ll see, but Wh (watt-hour) is a more accurate measure of total energy. Think of mAh as the size of the fuel tank and Wh as the actual amount of fuel. To convert mAh to Wh, you need the battery’s voltage (V), which is usually 3.7V for lithium-ion power banks. The formula is (mAh * V) / 1000 = Wh. For example, a 10,000mAh bank is roughly 37Wh. This Wh number is the one used for airline restrictions, so it’s good to know.
How should I store my power bank when not in use?
For long-term storage, don’t leave it fully charged or completely drained. I aim for a charge level between 40% and 60% and store it in a cool, dry place. This helps preserve the battery’s health and longevity. Extreme heat, like in a hot car, is one of the worst things for a lithium-ion battery, so I always keep it out of direct sunlight when I’m not on the trail.
